RELATED APPLICATION

The present application claims the benefit under 35 U.S.C. §119 of U.S.Provisional Patent Application No. 61/146,737 titled POULTRY SPURPROCESSING SYSTEMS AND METHODS and filed on Jan. 23, 2009, which ishereby incorporated by reference in its entirety.

Systems and methods for removing and/or retarding the growth of fourthtoes on birds/poultry are described herein.

The processing of poultry may include activities such as sexing todetermine gender, inoculating or otherwise medicating the birds, feedingthe birds, weighing the birds, treating the beaks and/or claws of thebirds (to, e.g., retard their growth), etc. Conventionally, birds arehandled manually, i.e., individuals must physically hold the bird andeither perform the process while holding the bird or load the bird intoequipment in which one of the processes is performed.

In many cases, the birds may be restrained by their heads as describedin, e.g., U.S. Pat. No. 5,651,731 (Gorans et al.) with the remainder ofthe bird being either manually restrained or unrestrained.

The fourth toe is an anatomical feature located on the shank of a bird,below the hock joint. In some instances, the fourth toe mayalternatively be referred to as the “hallux claw.” The remainder of thetoes (other than the fourth toe) are attached to the distal end of theshank and are the digits upon which the bird stands, while the fourthtoe or hallux claw is elevated on the shank above the toes used tosupport the bird.

Treatment of the fourth toes on birds is preferably accomplished asdescribed herein using one or more non-contact energy sources to directenergy onto the fourth toe such that its growth is retarded. It may bepreferred that the treatment include delivery of energy to the fourthtoe in amounts sufficient to retard fourth toe growth, but that does notdirectly remove the fourth toe (although the fourth toe may eventuallyseparate from the bird after treatment due to, e.g., tissue necrosis)

In one aspect, some embodiments of the fourth toe processing apparatusdescribed may include a shield comprising a first side and a secondside; a non-contact energy source emitting energy towards the first sideof the shield; a shank restraint structure proximate the second side ofthe shield, the shank restraint structure capable of receiving a shankof a bird located proximate the second side of the shield; and a fourthtoe aperture extending through the first side and the second side of theshield, such that energy emitted towards the first side of the shield bythe energy source passes through the fourth toe aperture in the absenceof an obstruction located in the fourth toe aperture, whereby a fourthtoe of a bird having its shank positioned in the fourth toe aperture isexposed to the energy.

DESCRIPTION OF EXEMPLARY EMBODIMENTS

In the following detailed description of exemplary embodiments,reference is made to the accompanying figures of the drawing which forma part hereof, and in which are shown, by way of illustration, specificembodiments in which apparatus, systems, and methods described hereinmay be practiced. It is to be understood that other embodiments may beutilized and structural changes may be made without departing from thescope of the present invention.

One exemplary embodiment of a fourth toe processing apparatus isdepicted in the perspective view of FIG. 1, the side view of in FIG. 2,and the exploded front view of FIG. 3.

Although the fourth toe processing apparatus 10 is depicted inconnection with a poultry carrier 50, it should be understood that thefourth toe processing apparatus 10 may be used without the depictedpoultry carrier, e.g., a different poultry carrier may be used, nopoultry carrier may be used, etc.

Referring to FIGS. 1-3, the fourth toe processing apparatus preferablyincludes a shield 10 having a first side 12 and a second side 14. Theapparatus further includes a non-contact energy source 20 emittingenergy towards the first side 12 of the shield 10. One or more shankrestraint structures 30 are provided proximate the second side 14 of theshield 10. The shank restraint structure 30 is preferably capable ofreceiving a shank of a bird located proximate the second side 14 of theshield 10 (as depicted in, e.g., FIG. 2). Although the depictedembodiment includes a pair of shank restraint structures, the apparatusmay, in some embodiments, include only one shank restrain structure.

A fourth toe aperture 40 extends through the first side 12 and thesecond side 14 of the shield 10 such that energy emitted towards thefirst side 12 of the shield 10 by the energy source 20 passes throughthe fourth toe aperture 40 in the absence of an obstruction located inthe fourth toe aperture 40. For example, if the fourth toe of a bird ispositioned in the fourth toe aperture 40, it would be exposed to energyincident on the first side 12 of the shield 10.

The shield 10 is preferably opaque to the energy emitted by thenon-contact energy source 20, such that the energy emitted by the source20 is incident only on the portions of the bird exposed within thefourth toe apertures 40. In other words, the shield 10 preferablyshields or protects the bird from the energy emitted from source 20.

Although the shank restrain structures used in connection with thefourth toe processing apparatus may take many different forms, e.g.,clamps, tubes, posts, etc. In the depicted embodiment, the shankrestraint structure 30 includes a channel formed in the shield 10. Thechannel may preferably be sized to receive a significant portion of theshank of a bird such that the shank is at least partially restrainedfrom movement. The channel may include slots or other features that areadapted to guide the fourth toes into the fourth toe apertures 40.

The shank restraint structure 30 may include one or more suctionopenings 32, wherein suction can be delivered to retain a bird shank inthe shank restraint structure 30 by connecting a suction device (e.g.,pump, bladder, etc.) to the suction openings. The suction openings 32may take any suitable form or shape, e.g., slots, circles, etc. In theembodiment as depicted in FIG. 3, each shank restraint structure 30includes two slots as suction openings 32.

In some embodiments, the shield 10 may include one or more passagewaysformed therein, wherein the passageways are in fluid communication withthe suction openings 32. The passageways may extend through the shield10 to a suction port on the shield, whereby a suction source can beplaced in fluid communication with the suction opening 32 through thepassageway.

As depicted, it may be preferred that the apparatus include two shankrestraint structures, wherein each shank restraint structure includes afourth toe aperture so that energy can be delivered to the fourth toeson both legs at the same time if desired. Although the shank restraintstructures 30 are in form of substantially parallel channels, the shankrestraint structures need not necessarily retain the shanks insubstantially parallel alignment with each other.

The fourth toe processing apparatus also includes a non-contact energysource 20. The depicted source 20 includes one or more bulbs 22 locatedin housing 24. The sources may further include reflectors 26 adapted todirect energy emitted by the bulbs 22 towards the fourth toe apertures40. Although a bulb is depicted in FIG. 2, the non-contact energysources 20 may take many different forms, e.g., any electromagneticenergy source, a heated fluid source (where, e.g., the heated fluid maybe in the form of a gas), a laser, etc. In some embodiments, theapparatus may include two or more different non-contact energy sourcessuch that two different types of non-contact energy can be delivered tothe fourth toes, with the two types of energy being delivered at thesame time and/or at different times.

In some embodiments, the fourth toe processing systems may be designedto interface with a bird restrained in a poultry carrier such as thosedescribed in, e.g., U.S. Provisional Patent Application Ser. No.61/146,732, titled POULTRY CARRIERS AND METHODS OF TRANSPORTING POULTRY,filed on Jan. 23, 2009 and in PCT Patent Application PCT/US10/21900,titled POULTRY CARRIERS AND METHODS OF RESTRAINING POULTRY, filed oneven date herewith.

The poultry carriers used in connection with the apparatus describedherein may preferably atraumatically restrain a live bird. As usedherein, the term “atraumatic restraint” (and variations thereof) meansrestraint that does not require puncturing the skin of the bird torestrain the bird.

One exemplary embodiment of a poultry carrier that may be used inconnection with the apparatus and methods described herein is depictedin. FIGS. 1-5. The poultry carrier 50 is operably supported above a base90 by a post 92. The base 90 and support may be provided such that thepoultry carrier 50 can be used with conveyors and other transportsystems.

The depicted poultry carrier 50 also includes a torso support element60, a leg clamp apparatus including one or more leg clamps 70 and anoptional head support 80. The various components may be operablyattached in a manner that provides for atraumatic restraint of a birdpositioned in the poultry carrier 50.

In at least some embodiments, the torso support element 60 includes asupport surface that is preferably shaped to generally follow theanatomical shape of the torso of a bird located in the poultry carrier50. As a result, the shape of the support surface may be differentdepending on the breed, age, gender, etc. of the birds that are to berestrained in the poultry carrier 50.

The poultry carrier 50 may also include a leg clamp apparatus with oneor more leg clamps 70 positioned to restrain the legs of a bird havingits torso supported by the torso support element 60. The leg clamps 70may preferably be positioned to retain the leg of a bird on the thigh ata location above the joint commonly referred to as the “hock” joint. Theleg clamps 70 may include arms that move between open configurations inwhich the thighs of a bird can be positioned in the leg clamps andclosed configurations in which the thighs of the bird are retained inthe clamps 70. Although the depicted leg clamps 70 include arms, otherstructures (such as, e.g., inflatable bladders, etc.) may be used toretain a bird's thighs in the leg clamps when the clamps 70 are in theclosed configuration.

The poultry carrier 50 may include separate leg clamps for each leg of abird as in the depicted embodiment. Alternatively, the leg clampapparatus may include a single leg clamp that is preferably capable ofcapturing and retaining at least one or preferably both legs of a bird.One potential advantage of separate leg clamps is that they maypotentially be used independently of each other such that one leg of thebird may be restrained first, followed by capture of the other leg.

The leg clamps 70 may be normally closed, but constructed such that theyopen in response to the forces generated as a leg is being inserted intothe leg clamp 70 (the leg clamps 70 may be spring-loaded, etc.). Inother embodiments, the leg clamps 70 may have defined open and closedconfigurations between which the clamps can be moved to accept and/orretain a leg of a bird being restrained.

The poultry carrier 70 may also optionally include a leg separatorpositioned between the leg clamps 70. The leg separator may be used inconnection with the leg clamps and the torso support element 60 toprovide more accurate and repeatable positioning of the bird within thepoultry carrier 50. The leg separator may also assist in positioning thelegs of the bird to facilitate capture of the legs in the leg clamps 70.

The portion of the leg separator facing upwards towards the torsosupport 60 and head support 80 may preferably be concave such that therump of a bird restrained in the carrier 50 nests into the leg separatorto at least partially restrict movement of the restrained bird's rumpside-to-side, i.e., in a direction extending between the leg clamps 70in the depicted embodiment. The leg separator is in the form of an openloop, although in other embodiments, the leg separator may be formed ofany structure that provides a concave cavity into which the rump of thebird may nest to restrict movement of the rump.

The poultry carriers 50 may also include a head support 80 operablyattached to the torso support element 60 and positioned to support thehead of a bird located in the poultry carrier 50. The head support 80includes a first side facing the head of a bird retained in the carrier.

The head support 80 may include a head clamp movable between an openconfiguration and a closed configuration. In the open configuration, thehead clamp is preferably positioned such that the head of a bird can bepositioned in the head support 80. In the closed configuration, the headclamp preferably functions to retain the head of a bird in the headsupport 80. The head clamp may preferably extend far enough towards thelegs of the bird such that it is capable of restraining the neck of thebird when the head clamp is in the closed configuration.

Structures similar to the head support 80 and related components may bedescribed in, e.g., U.S. Pat. No. 5,651,731 titled METHOD AND APPARATUSFOR DEBEAKING POULTRY; U.S. Pat. No. 7,232,450 titled APPARATUS ANDMETHOD FOR UPPER AND LOWER BEAK TREATMENT; U.S. Patent ApplicationPublication US 2005/0101937 A1 titled APPARATUS AND METHOD FOR NASALDELIVERY OF COMPOSITIONS TO BIRDS; U.S. Pat. No. 7,363,881 titled BEAKTREATMENT WITH TONGUE PROTECTION; etc.

The poultry carrier 50 may include a base 90, with the torso supportelement 60 and the base 90 being operably attached to each other in amanner that allows the torso support element 60 to be moved between twoor more different orientations or configurations relative to the base90. In the depicted embodiment, the torso support element 60 is attachedto the base 90 using a post 92 or other support structure, althoughother attachment structures may be used. The different orientations orconfigurations may provide for improved access to different portions ofthe bird's anatomy such that different procedures may be facilitated. Inother words, a portion of a bird's anatomy may be more easily accessedif the bird is in one or more selected orientations.

The torso support element 60 can preferably move between and be held in,e.g., an upright configuration (as depicted in, e.g., FIGS. 3 and 4) andan inverted configuration (as depicted in, e.g., FIGS. 1, 2, and 5).Although these two configurations are depicted, other intermediateconfigurations may also be used (where, e.g., the bird is held in supineor prone position). Movement between the two configurations may beaccomplished by. e.g., rotating the torso support element 60 and thebase 90 relative to each other. In the inverted configuration the legclamp apparatus 70 is located closer to the shield 10 than when thetorso support element 60 is in the upright configuration.

Movement of the torso support element 60 between the upright andinverted configurations may be accomplished, in some embodiments, byrotating the torso support element 60 and the base 90 relative to eachother (although it may be typical to rotate the torso support element 60while the base 90 remains relatively stationary). The carriers 50 mayinclude torso support elements 60 that are designed to rotate about awide variety of angles, e.g., horizontal axes, vertical axes, cantedaxes, etc. One potentially useful axis of rotation may include, e.g.,axis 11 as seen in FIGS. 4 and 5.

Rotation of the torso support element 60 about axis 11 from the uprightconfiguration to the inverted configuration may be limited in a firstdirection by a stop pin that protrudes from the torso support element60. The stop pin may preferably act against a stop surface 69 oncarriage 68 that supports the torso support element 60. Althoughrotation of the torso support element 60 is limited using a stop pinacting on stop surface 69, the stop pin and stop surface 69 representonly an example of the myriad of structures that could be used tocontrol rotation of the torso support element 60.

Rotation of the poultry carrier 50 (and, thus, a bird restrained in thepoultry carrier) may be useful in connection with the fourth toeapparatus described herein because it may be used to place therestrained bird's shanks in an orientation that allows for better andeasier placement with respect to the shield 10 and the shank restraintfeatures located thereon.

In addition, the leg clamp apparatus 70 of the poultry carrier 50 maypreferably restrain a bird's legs such that the distance between theright and left shanks matches the distance between the shank restraintfeatures (e.g., channels 30) of the apparatus described herein.

Methods of using the apparatus and systems described herein may includepositioning a shank of a bird in a shank restraint structure proximate asecond side of a shield that comprises first and second sides. Themethod may further include locating the fourth toe on the shank of thebird in a fourth toe aperture that extends through the first and secondsides of the shield such that the fourth toe in the fourth toe apertureis exposed on the first side of the shield. Non-contact energy can beemitted towards the first side of the shield such that at least aportion of the non-contact energy is incident on the fourth tow locatedin the fourth toe aperture.

In some methods described herein, the shank restraint structurecomprises a channel formed in the second side of the shield and thefourth toe aperture is located in the channel as described herein. Thepositioning may involve placing the shank of the bird in the channel ofthe shank restraint structure such that the fourth toe on the shank islocated in the fourth toe aperture as described herein (see, e.g., FIG.2). If the shank restraint structure also include a suction opening asdescribed here, the method may include drawing a suction on the suctionopening to assist retention of the shank in the shank restraintstructure (by the vacuum forces generated from the suction).

In methods that include the use of the optional poultry carriersdescribed herein, the method may further include atraumaticallyrestraining the bird in the poultry carrier that includes a torsosupport element and leg clamp apparatus as described herein toatraumatically restrain the torso and the legs of the bird. The torsosupport element may be pivotally attached to a base as described hereinsuch that the torso support element and the leg clamp apparatus can berotated relative to the base about an axis of rotation.

The method may further include rotating the bird in the poultry carrierfrom an upright configuration to an inverted configuration, wherein inthe inverted configuration the leg clamp apparatus is located closer tothe shield than when the torso support element is in the uprightconfiguration. That rotation can provide better access to the bird'sshanks. The rotating can be performed before or at the same time as theshank of the bird is positioned in the shank restraint structure.

The fourth toe processing apparatus may be manufactured of any suitablematerials, e.g., metals, plastics, etc. In some instances, it may bebeneficial if the materials have selected physical characteristics, suchas, e.g., electrical conductivity, thermal conductivity, etc.
